Limestone applied at the rate of 6.7 metric tons/ha to a raw peat soil (pH 3.7) increased the yield of potatoes in a field experiment by 5.5 tons/ha. Higher rates of lime gave no further increase. In the three subsequent years the yield was just as satisfactory on the unlimed plots as on those receiving the 6.7-ton rate and the yield was depressed by higher rates of lime.Limestone, particularly at the higher rates, tended to increase hygroscopic moisture, volume weight, ash, CEC and solubility in pyrophosphate solution and to decrease C and the C/N ratio of the soil. Although these changes were small they were indicative of a beneficial effect of lime on humification of the peat.

Development of oil palm plantation on peatland was faced with hydrophobicity problem caused by over drained. Hydrophobicity could reduce water retention and nutrient availability in the peat soil. Beside of proper water management application, addition of soil ameliorant which contain iron could increase stability and improve peat soil fertility. The study was conducted to obtain the effect of steel slag on peat soil properties and hydrophobicity. In this study, peat soil was incorporated with steel slag and incubated in 60 days period. The research was employed completely randomized design (CRD) factorial 2 x 2 x 4. First factor is peat maturity consists of two levels: sapric (S) and hemic (H), while the second factor is soil moisture which also consist of two levels: field capacity (W1) and dry (under the critical water content) (W2). The third factor is steel slag dosage which consist of four levels: 0 g pot (TB0), 7.17 g pot (TB1), 14.81 g -1 -1 pot (TB2), and 22.44 g pot (TB3). The result showed that application of steel slag significantly increase of soil pH, ash content, and water retention at pF 4.2. Furthermore, application of steel slag significantly reduce time for water reabsorption (wettability) in sapric. On the other hand, there are negative corellation between water penetration and soil pH, ash content, and water retention at pF 4.2. Overall, application of steel slag could increase wettability and prevent peat soil hydrophobicity.

We studied the microflora of Quebec sphagnum peat moss samples taken from five different locations in a peat moss processing plant: soil, drying stacks, sedimented dust (walls and floor), and in bagged peat moss. Large numbers of microorganisms were found; the predominant ones were of the genus Monocillium (up to 112 × 106 colonies/g of dry peat) and the genus Penicillium (320 × 104 colonies/g dry weight). These moulds were more abundant in the processed peat moss than in the peat soil (e.g., Monocillium: soil, 138 × 103; processed peat, 112 × 106). Aspergillus spp. were absent in all five sample sites. We conclude that Quebec peat moss contains large quantities of microorganisms and that moulds become more concentrated during the processing of the peat from the soil to the final product.

The low yield of rice in thick peat can be overcome by provisioning complete nutrients. Various efforts have been made to increase the productivity of Indonesian peatlands, one of which is by adding salted fish waste and cow manure. This research was carried out on a plastic house scale from October 2017 to January 15, 2018, in Pelalawan District, Pelalawan Regency, Riau. This research was arranged in a Completely Randomized Design (CRD), consisting of eight treatments, namely L0 = Control, L1 = 1.5 ton.ha-1 of fish waste, L2 = 2.25 ton.ha-1 of fish waste, L3 = 7 tons/ha of cow manure, L4 = 15 ton.ha-1 of cow manure, L5 = 1.5 ton.ha-1 of fish waste + 7 ton.ha-1 of cow manure, L6 = 1.5 ton.ha-1 of fish waste + 15 ton.ha-1 of cow manure, L7 = 2. 25 ton.ha-1 of fish waste + 7 ton.ha-1 of cow manure, and L8 = 2.25 ton.ha-1 of fish waste + 15 ton.ha-1 of cow manure. The results showed that the application of cow manure and salted fish waste could increase soil pH, total NPK, and NPK uptake. The application of 2.25 tons/ha of fish waste and 15 tons/ha of cow manure resulted the best results in soil pH, total NPK, and NPK uptake, therefore it is recommended for the cultivation of lowland rice on peat soil.

Chemical analysis, including a conventional scheme of proximate analysis as well as pre-treatment with 0.1 N hydrochloric acid, were used to assess changes occurring in the chemical properties of a strongly acid sphagnum peat when it was limed, fertilized and cropped for 3- and 5-year periods. Pre-treatment was necessary to remove the large quantities of added fertilizer and limestone which were found to neutralize substantial amounts of the hydrochloric acid required for the hydrolysis of hemicellulose.In comparison with raw peat the percentages of hemicellulose and cellulose and the carbon-nitrogen ratio decreased in the cropped peat. The situation was reversed in the case of bitumen, the lignin-humic substances complex and cation-exchange capacity. The results indicated further that with cropping the composition of the peat tended towards the composition of an adjacent muck.

A three-year field experiment was conducted from 2000 to 2002 in North-East Poland. Each year three sulphur fertilization rates in the form of sulphate (S- SO<sub>4</sub><sup>2–</sup>) and pure sulphur (S-S<sup>0</sup>) were applied: 40, 80 and 120 kg/ha. The most beneficial effect on the yields of cabbage, onion and barley was produced by the rates of 40 and 80 kg S/ha, while the dose of 120 kg S/ha (especially when applied as S-SO<sub>4</sub><sup>2–</sup>) reduced the yields of these crops. Increasing rates of sulphur used as a fertilizer caused increased concentration of sulphates in plants up to their luxury accumulation. Irrespective of the test crop species or form of sulphur applied, once the crops terminated their vegetative season, the plants fertilized with sulphur typically contained more total N than those fertilized only with NPK. The S-SO<sub>4</sub><sup>2–</sup> fertilization tended to raise the accumulation of N-NO<sub>3</sub><sup>–</sup> in the crops, especially during the juvenile phase. The application of 120 kg S-SO<sub>4</sub><sup>2–</sup>) /kg caused depressed amounts of potassium in cabbage, onion and in barley during the heading phase.

Abstract. In a field experiment to investigate potential impacts of climatic change, a small area of flush wetland in Wales was subjected to three successive years of simulated summer drought/rewetting (autumn-spring) cycles (1992–94). Drought was simulated achieved by diverting stream water around the experimental wetland during the summer, so that the wetland received only precipitation inputs during that time. The effects on peat-water chemistry in the rhizosphere were monitored at regular intervals until spring 1996, and comparisons made with a control. Simulated summer drought decreased, significantly, the natural summer peaks in dissolved organic carbon (DOC) and iron, whilst subsequently increasing the natural autumn-winter peaks in sulphate concentrations and acidity in the peat water. The effects of simulated drought on SO4 concentrations in the peat water compared favourably with subsequent events monitored following a natural summer drought in 1995. Autumn-winter peaks in SO4 concentrations in the control wetland following the natural drought were of similar magnitude to those induced by the drought simulated in the experimental wetland in the previous three years.

The effect of liming alone or in combination with N, K, and Mg on the growth of white spruce (Piceaglauca (Moench) Voss), on the nutrient status of needles of trees, as well as on the content of mineral elements in the soil, was studied. The study, carried out in 1972, indicated that the soil amendments applied in 1962 at Grand'Mère in a 36-year-old plantation at the rate of 336 kg hydrated lime, 115 kg N, and 93 kg K, with or without 22 kg Mg per hectare, gave significantly higher basal area increments than those in the controls. Without the inclusion of N and K, dolomite or hydrated lime alone or with Mg had no marked beneficial effect on the growth of white spruce 5 or 10 years after treatments. No appreciable residual effect on the nutrient status of needles could be established. However, the amendments had slightly increased the soil pH and the soil content of exchangeable Ca in the treated plots.

Pesticides are widely used in agriculture, including on peat soil. The objective of this study was to analyze the effect of the application of paraquat, difenoconazole, and butylphenyl methylcarbamate (BPMC) on CO2 emissions and concentrations of phenolic acids in a peat soil. Peat soil sample was taken in District of Pulang Pisau, Central Kalimantan. The peat soil was applied with 1.89 mg kg-1 paraquat, 1.72 mg kg-1 difenoconazole and 1.65 mg kg-1 butylphenyl methylcarbamate (BPMC), then the soil was incubated for 1, 2, 4 , 5, 7, 10, 14, 21, 26 and 30 days. The results showed that the application of pesticides on peat soil increased CO2emission, and decreased CH4 emission and phenolic acid concentrations up to 30 days of incubation. The CO2 emmisions were derived from C of degraded pesticides and from C of phenolic acids, although the oxidation reaction was not accompanied by the change of soil pH. Keyword: CO2 emission, phenolic acids, butylphenyl methylcarbamate (BPMC), difenoconazole, paraquat, peat soil
